Title: Printing head
Inventor: OOTSUKA HIDEFUMI
IPC: H01F7/14
Filed: 1983-05-04
Abstract: PURPOSE:To make it possible to perform good printing operation even after heat generation, by providing a member high in expansion coefficient to a yoke for forming a magnetic path along with a permanent magnet in the printing head of a wire head system. CONSTITUTION:Members each high in expansion coefficient are used to yoke pieces 5a-5c forming a magnetic path along with a parmament magnet in a printing head. By using said member, an inside temp. including the yoke piece 5c becomes higher than an outside temp. including the yoke piece 5b by heat generating during printing operation, In this case, even if each member expands, the attraction surfaces of the yoke pieces 5c, 5b are closely contacted with an attraction member 2 on the same plane in spite of temp. difference because the expansion coefficient of each member 11 is high. By this mechanism, because the expansion difference due to the difference of temp. distribution in the printing head can be compensated, the printing head can be driven without generating the unsymmetric impact between the lever part of the printing head and the attraction surface thereof and the life of the printing head is prolonged and the reliability thereof is enhanced.

Title: Ultrasonic probe
Inventor: KIMURA TOMONORI
IPC: H04R1/34
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce a multiecho and also to improve the accuracy of a flaw detection result in the inspection of a specimen with an ultrasonic wave, by forming an ultrasonic transfer part with polyethylene resin having an acoustic impedance of at most twice the acoustic impedance of an acoustic coupling medium. SOLUTION: Water is used for an acoustic coupling medium 4. A longitudinal wave excited by an oscillator is propagated in a wedge 3, and reflected and refracted at a boundary surface 21. Then the transmitted longitudinal wave is propagated in the acoustic coupling medium 4. Where the ultrasonic wave is made incident from the water to acrylic resin, 37% of the sound pressure is reflected. In the case from the water to polyethylene resin, only 8.36% of the sound pressure is reflected, and therefore the level of the reflected wave is reduced. The highest acoustic impedance of the polyethylene resin is 2.00, and the ratio thereof to the acoustic impedance 1.48 of water is 2.02.  Consequently, multiecho is reduced and an accurate flaw detection test can be carried out, because the ratio of the acoustic impedance of the polyethylene resin to it of the acoustic coupling medium can be 2.0 or less by using the polyethylene resin for the wedge 3.

Thus, the delay time is reduced and the difference in the response frequency due to the difference in the setting value of the 1st and 2nd comparators 5,10 is reduced more than a conventional counter.

Title: Digital temperature compensation type piezoelectric oscillator
Inventor: KUDO TETSUO
IPC: H03L1/02
Filed: 1986-04-07
Abstract: PURPOSE:To decrease the change in the oscillated frequency by using an output of a voltage converter so as to control a voltage controlled piezoelectric oscillator thereby averaging an output of the controlled voltage of the oscillator. CONSTITUTION:A temperature compensation digital code corresponding to a digital code of an analog/digital converter 2 being e temperature address signal is stored in a memory circuit 3 to compensate the frequency temperature characteristic of the voltage controlled oscillator 5 in advance, and when the ambient temperature is changed, the address signal is also changed and a temperature compensation code is read out of the memory circuit 3. The temperature compensation digital code read in this way is fed to a digital/analog converter 4, where the signal is converted into a stepwise analog signal, which is fed to a voltage converter 6. Thus, the stepwise analog signal is averaged by the voltage converter 6 and its output is fed to the voltage controlled piezoelectric oscillator 5 as a control voltage.

Abstract: PURPOSE:To obtain an optical fiber connector which can detach and connect optical fibers with small loss and with high density in a small size by combining and using a split sleeve for aligning the axis of a ferrule and a leaf spring with which the tight adhesion of an end face is enhanced. CONSTITUTION:In the case of connecting two optical fibers 21a and 21b, the optical fibers 21a and 21b are respectively inserted in the ferrules 23a and 23b and the end faces ground.

IPC: H01L23/29
Filed: 1991-02-18
Abstract: PURPOSE:To prevent a metal such as aluminum wiring from being corroded by improving moisture resistance of a semiconductor device by blocking water contents entering the inside of a semiconductor chip from its side surface. CONSTITUTION:A groove 15 reaching a field oxide film 11 on a semiconductor substrate 10 below an insulation film 13 is formed at the insulation film 13 of a non-element region between one side of a semiconductor chip (right-side surface a of figure) and a bonding pad (not illustrated) which is formed opposite to it. Then, a wire 16 and an insulation film 17 are formed on this insulation film 13. The insulation film 17 enters this groove 15 and cuts contact between the insulation film 17 and the insulation film 13 at a groove bottom portion. Therefore, when adhesion property between both is poor, water contents intrude into an element region from a side surface A through an interface of both. However, intrusion of water contents is prevented by the groove 15. A metal film may be used instead of the groove.

IPC: H01L25/07
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To easily connect a terminal for external connection to an external wiring and increase the adhesion between the terminal and the external wiring by forming, in an upper face of a case, a recess having a slope at the side toward which the terminal for external connection is bent. SOLUTION: In a semiconductor module for power, a recess 6a is formed in an upper face of a case 6 and the recess 6a is provided with a slope 6b at the side toward which a terminal 4 for external connection is bent. The terminal 4 for external connection is bent along the slope 6b of the recess 6a and then is bent along the upper face of the case 6. Therefore, the terminal 4 for external connection is bent at 90 deg. in the form of curve at a section 4a through which the terminal for external connection is extracted. The slope 6b may be either straight or curved. By this method, a horizontal line is obtained between the end 4b of the terminal for external connection and a nut 8 for fixation and thereby an external wiring can be easily connected to the terminal 4 for external connection and the adhesion between the terminal and the external wiring can also be increased.

Abstract: PURPOSE:To enhance productivity and to simplify the titled apparatus, by arranging an equilibrium support apparatus so as to embed the same under the surface of the bed provided to the under-surface of a bolster. CONSTITUTION:Equilibrium support apparatuses 8 are respectively arranged vertically so as to be embedded in a bed part 5. When supports part 9 are protruded above the surface of the bed 5, a slide 4 can be supported in an equilibrium state through intermediate support materials 16 inlaid with and inserted into a bolster 11 and the press molding of a plastic material 10 can be performed with desired high accuracy. When the support parts 9 are drawn in under the surface of the bed after the completion of press molding, the bolster 11 can be fed out to the side of lateral supply and feed-out apparatuses 17 along a slide rail 19. As a result, because a pair of the equilibrium support apparatuses 18 will be suffice and can be fixed to the bed part 5 without movement, the hydraulic piping or electric wiring of the equilibrium support apparatuses 8 may not be moved along the bolster and equipment becomes simple.
